Abstract

The effect of Kehan 98 hydrogel on the stem water potential and growth of Pinus elliottii under water stressed and the effects of Kehan 98 hydrogel , Black Gold hydrogel and Stockosorb 400k hydrogel on the growth of Pinus taeda were studied .The results showed that Kehan 98 hydrogel could significantly reduce the water stress by increasing stem water potential of Pinus elliottii .Under the stress , the stem water potential of the pine seedlings treated with the hydrogel was 0.27 -0.87 MPa higher than the control group .Higher the stress was , more significantly the difference between the two groups was .The height and stem growth of Pinus elliottii were improved after it was treated with the hydrogel .The dry matter contents of the roots and above-ground parts , root-top ratio of Pinus elliottii were all higher than the control group .Pinus elliottii seedlings treated with hydrogel grew very well. The height , diameter at ground height , water contents of stems and leaves of Pinus taeda were a bit higher than the control group after them had been treated with Kehan 98 hydrogel , Black Gold hydrogel and Stockosorb 400k hydrogel for nearly three months .However , the effects of the three hydrogel were not fully played and there was no significant difference between the two groups because of the limited experimental environment .[ Ch , 1 fig .3 tab . 11 ref .]
